Question

A car accelerate uniformly from 18 km/ hr .36 km /hr .in 5 seconds .calculate the accelerate​

Answer 1

Answer:

1 m/s^2 is acceleration

Explanation:

u = 18km/h = 18*5/18 = 5m/s

v = 36km/h = 36*5/18 = 10m/s

acceleration = v-u  / t

                     = 10-5  /t

                     = 5/5 = 1m/s^2

Answer 2

Answer:

1 m/s2

Explanation:

v = 36 x 5/18 m/s = 10 m/s

u = 18 x 5/18 m/s = 5 m/s

Hence, a = (10-5)/5 m/s2 = 1 m/s2
